Windows Phone 7 (Mango) App gets disconnected when put in background?

 

Can I prevent my application from having the sockets closed when the user puts it in the background on Windows Phone 7 Mango?

If so, how would I go about doing it?

Thanks

No, you cannot keep a persistent socket connection open when your application is not running, even in Mango.

You can:

  • Create a PeriodicTask that will be called every 30 minutes, but can only execute for 10-15 seconds before being killed
  • Create a ResourceIntensiveTask that will run when the phone is connected to power and will execute for as long as you like (or until the phone is disconnected from power)

    • Both types of task have access to your application's isolated storage but will execute in a separate application domain, so it won't have access to variables and other application state.

    you should implement a background task - there is a sample on the interwebz on how to do that

    -- edit -- but still that will be called every 30 minutes sooo... unless you are streaming something (there is a specifi task for that) you are out of luck
